APPARATUS FOR DEEP BORING.

SPECIFICATION forming part of Letters Patent ive. 643,428, datedFebruary is, 1906.

Apnlieation filed M91611 4 1899. Serial No: 707,748. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH VoeT, manufacturer, a subject of the GermanEmperor, and a resident of Niederbruck, near Masmiinster, Alsace,Germany, have invented new and useful Improvements in Apparatus for DeepBoring, of which the following is a full, clear, and exactspecification.

My invention relates to improvements in apparatus for boring at greatdepths in which the boring-tool or cutter is rigidly connected to thebore-rod, which is actuated by a rocking beam.

I will describe myimprovements with ref erence to the accompanyingdrawings, in which, by way of example, they are applied to aconstruction of boring apparatus in which springs are interposed betweenthe bore-rod and the actuating-beam, as also between this and thedriving connecting-rod.

Figures 1 and 2 show, respectively, a side view and a front view of theapparatus, both views being partly in section. Figs. 3 and 4 show, to alarger scale, detail views of parts of ed by means of two screws D D,held by screw nuts I), carried by the sliding support E,which can beshifted horizontally upon the uprights F by means of a horizontalscrew-spindle 0, carried in a plate 6, fixed to the uprights F. Thescrew-nuts b are formed as worm-wheels at their periphery and gear witha worm f.

To the uprights F are fixed plates R, having vertical grooves 1 1, 2 2,-3 3 communicating at bottom with a horizontal groove g, and the ends ofthe trunnions a of the beam are provided with blocks 9, which areadapted to slide in one or other of the grooves l 1, 2 2,

or 3 3, into which they may be brought by' first shifting them along thehorizontal groove g by means of the screw 0 and then raising them in therequired vertical groove by means of the worm f, which actuates the nutsb of the suspension-screws D. Thus assuming the trunnions a of the beamto be in the position shown in full lines at Figs. 1 and 2, then onturning the worm f they may be brought to the position a, and on thenturning the screw 0 they can be brought either into the position at orinto the position 01.. On then again turning the worm the trunnion ofthe beam can be brought either to the position a or into the position athese several positions of a be-' ing indicated in dotted lines in Fig.1.

It will be seen from the above description that in shifting thetrunnions a of the beam from the grooves l l of the uprights F to thegrooves 2 2 or 3 3 (the trunnions having pre viously been disconnectedfrom the beam in any suitable manner) the stroke of the borerod P willbe diminished, while if the trunnions a be shifted from the grooves 3 3to the grooves 2 2 or 1 1 the stroke of the bore-rod P will beincreased, so that by this means the action of the boring apparatus canbe adapted to suit strata of different hardness through which the boringhas to be made without requiring to replace the crank-shaft G by anotherfor imparting to the connecting-rod a different length ofstroke, whichoperation would cause a considerable loss of time.

When diminishing the stroke of the bore-rod, v

its speed can be increased.

The pivot h of the connecting-rod B, Figs. 1 and 4, is fixed in abearing 11, fixed on a plate I-I, resting on the springs I, which havefor their object to deaden the shocks which the connecting-rod tends toimpart to the beam on starting the upward motion of the bore-rod. On theplate H rest counter-springs l, and the tension of these springs I and Ican be regulated by means of screw bolts and rests the bore-rod P andwhich have the ob ject of deadening the shocks which the borerod tendsto impart to the beam A at the free fall of the former, are alsocombined with counter-springs M, placed beneath the beam A, and thetension of these springs M M can be regulated according to the weight ofthe bore-rod by means of screw bolts and nuts N.

The springs M prevent any sudden upward jerks of the bore-rod when it isbeing raised. By thus deadening the several shocks to which theapparatus is liable any damage to the bore-rod is prevented, and thespeed of working can be increased.

What I claim is- 1. An apparatus for deep boring, havingasupporting-frame provided with horizontal grooves, a rocking beamsupported in said frame, a boring-rod suspended from one arm of saidbeam to receive a boring-tool, and operating means coupled to theopposite end of said beam, of two trunnions for the beam, movable alongthe same in the horizontal grooves in the frame, and a screw forshifting the said trunnions along the frame, whereby the fulcrum of thebeam is adapted to be shifted without moving the beam eitherlongitudinally or vertically, substantially as set forth.

2. In an apparatus for deep boring, the combination with thesupporting-frame, and the rocking beam mounted thereon, of the connectedtrunnions of the beam, and screws for raising and lowering the trunnionsand for shifting them along the supporting-frame, said frame having, ateach side of the beam, a plurality of vertically arranged keepergroovesto receive the trunnions, said grooves being connected by a horizontalgroove, substantially as and for the purposes set forth.

3. In an apparatus fordeep boring, the combination with thesupporting-frame, the roclcing beam A, and the sliding support E, of theconnected trunnions a of said beam, the two upright suspension-screws DD, coupled to the trunnions and having on them wheelnuts 12; the groovedplates on the frame to receive the trunnions, the adjusting-screw c, andthe worm f, between and gearing with the wheel-nuts I), substantially asset forth.

4. In a deep-boring apparatus, the combination with the frame, therocking beam, the connecting-rod coupled to one arm of the beam, themeans for operating said rod, and the rigid boringrod carried freely bythe other arm of said beam, of the springs M, interposed between theboring-rod on the upper side of the beam, the counter springs M, at thelower side of the beam, to prevent the transmission of shocks from theboring-rod to the beam and from the latter to the rod, and screw-boltsN, which extend through the beam and the oppositely-arranged springs,for simultaneously and uniformly varying the tension of the springs,substantially as set forth.

5. In a deep-boring apparatus, the combination with the frame, therocking beam, the rigid boring-rod supported freely on one arm of thebeam, the connecting-rod B, and means for operating said rod, of theplate II, to which the upper end of the rod B is coupled, the springs I,under said plate and between it and the beam, the counter-springs Iresting on the plate H and opposite, respectively to the springs I, thescrew bolts extending through the beam and the respective springs, andthe nuts thereon for regulating the tension of the springs,substantially as set forth.

6. In a deep-boring apparatus, the combination with the frame, therocking beam mounted therein,the boring-rod coupled to one arm of thebeam,the connecting-rod coupled to the other arm of the beam, and meansfor op erating the connecting-rod, of the plate to which the connectingrod is coupled, the springs between said plate and the beam, thecounter-springs on the opposite side of said plate, means for couplingsaid springs and plate to the beam, and for regulating the tension ofthe springs, the cushion-springs M, of the boring-rod, thecounter-springs M, of said rod, and means for coupling said springs tothe beam and for regulating the tension of the springs, substantially asset forth.

'7. In a deep-boring apparatus, the combination with the frame, therocking beam mounted therein, the rigid boring-rod resting freely uponone arm of the beam, the connecting-rod coupled to the other arm of thebeam and means for operating the connecting-rod, of the plate H to whichthe connecting-rod is coupled, the springs I between said plate and thebeam,- the counter-springs I on the opposite side of said plate, meansfor coupling said springs I, I and plate II to the beam and forregulating the tension of the springs I, I, the cushion-springs M of theboring-rod, the counter-springs M of said rod, and means for couplingsaid springs M, M to the beam and for regulating the tension thereof,substantially as set forth.

In witness whereof I have hereunto signed my name, this 4th day ofFebruary, 1899, in the presence of two subscribing witnesses.
